IMPROVEMENT IN ADJUSTABLE GRA|NSPOUTS.

Specification forming part of Letters PatentNo. 213,278, dated March 18,1879; application iled December 19, 1878.

To all whom t may concern:

Be it known that I, FRANK M. CAMPBELL. of St. Louis, in the county ofSt. Louis and State of Missouri, have invented a certain new andImproved Adjustable Grain-Spent; and I do hereby declare that thefollowing is a full, clear, and complete description of the same.

The object of this invention is to conduct grain from an elevator intorailway cars and into the holds of vessels, whereby the said grain is1distributed evenly into the car and vessel, thus avoiding the shovelingand moving of the grain after being discharged therein.

A full and complete description of the said invention is as follows,reference being had to the accompanying drawings for illustrating thesame, in which- Figure 1 is a side view of the spout eX- tended. Fig. 2is a view of the spout closed up. Fig. 3 is a detached section.

Like letters of reference refer to like parts in the several views.

The said invention is an improvement on a grain-spout for which a patentwas granted to ine July 16, 1878.

The grain-spout referred to consists of a series of short tubes, A,which may be more or less in number, according to theI required lengthof the spout. Said tubes are tapering, so that the smallerv end of theone will t loosely in the larger end of the other. The difference in thediameter of the two ends of the tubes thus inserted one in the other issuch as to allow considerable play, so that the series of short tubeswill form a iiexible elongated spout, as shown in Fig. 1, susceptible ofbeing turned sidewise in any direction, and of being shortened up ortelescoped, as shown in Fig. 2.

The several sections or short tubes of the spout are connected to eachother by a number of short chains, B, one end of which is attached tothe larger end of one section of the spout, and the other attached tothe larger end of the section, in which the smaller end of the firstsection is inserted, substantially as shown in the drawings, in which itwill be seen that a series of connectingchains are arranged on the twoopposite sides of the spout,

thereby linking the whole series of short tubes strongly and securely toeach other, at the same time permitting a free movement of the series oftubes for being turned about in either direction and for being shortenedup, as show-n in Fig. 2. Connecting-chains maybe arranged on three sidesof the spout, instead of on two sides, in the event the spout be oflarge size, or even more depending upon the section and size.

C represents the lower end of the grain con ductor or chute, to whichthe ilexible spout above described is attached, as follows: Around theouter edge of the tubular end D of the conductor C is formed a narrowflange, a, Fig. 3, the diameter of which is sufficient to fit loosely inthe collar E of the spout. Around the inner upper edge of the collar isformed a narrow flange, b, which, when the two parts are put together,prevents them from being pulled apart, as the two flanges lock the twosections together, as shown in said Fig. 3. This connection of the twoparts forms a swivel-joint, so that the series of short tubes connectedto the end of the conductor can be turned easily and entirely around.

The collar E may be straight, as shown in Fig. 1, or slightly tapering,as seen in Fig.

vMy patented grain-spout, above alluded to, consists of a series oftapering tubes or sections like those herein described; but instead ofbeing attached to each other with chains they were connected to eachother by pivots, one on each side of the sections. This pivotal joiningof the sections together permitted the spout to bend only in twodirections, backward and forward from the line of their pivotalconnections, hence the spout could distribute the grain in twodirections only without turning the entirespout in such other directionfor that purpose. entire spout required much labor and. time, especiallywhen discharging grain. Furthermore, the sections being pivoted to eachother, the spouts could not be shortened up by telescoping them, toadapt the spout to the varying height of the place into which the grainwas being conducted. These objections are avoided by linking the severalsections coin posing the spout together with sectional nrt-cn,

This turning of the as will be'obvious,'a11ows the spout, eitherias awhole or sections thereof, to be'tnrned around in any direction, and tobe shortened up more or less, as the piace into which `the grain isbeing discharged lls up.

What I claim as my invention, and desire to secure by Letters Patent,is-

In grain-spouts for elevators, the tapering` sections A, inserted oneWithin the other, 'and connected together by short sectional chains,arranged in two or more sides thereof, andthe said sections attached tothe end of the conductor C by a swivelioint, substantially as hereindescribed, and for the purpose specified.
